Answer:

x =1 7/8

Step-by-step explanation:

2/3x−1/5x=x−1

Multiply by 15 to clear the fractions

15(2/3x−1/5x)=15(x−1)

10x - 3x = 15x -15

Combine like terms

7x = 15x -15

Subtract 15x from each side

7x -15x = 15x -15x -15

-8x = -15

Divide each side by -8

-8x/-8 = -15/-8

x =15/8

x = 1 7/8

Suppose the population of a town is 15,200 and is growing 2% each year. Write an equation to model the population growth. Predic
Dvinal [7]
<span><span>1.       </span>So the current population of the town is 15 200 and is growing per year with 2%.
Find the population number after 10 years.
First, let’s find the value of 2%  in decimal form
=> 2/100
=> 0.02

Now, let’s try to solve
Population = 15 200 ( 1 + (0.02 x 10) )
Population = 15 200 ( 1 + 0.2 )
Population = 15 200 + 3040
Population =  18 240
Thus, in 10 years, the town’s population will increase to 18 240.

A population of size 3,624 grows at a rate of 3% per year, compounded continuously. How big will the population be in 2 years?
rodikova [14]

Answer:

Step-by-step explanation:

The continuous compound formula is

y=Pe^{rt where P is the principle or starting value, r is the growth rate in decimal form, and t is the time in years. For us:

y=3624e^{(.03)(2)}\\y=3624e^{.06}\\y=3624(1.061836547)\\y=3848.09

which would probably round to just 3848 people.

Find the x and y intercept of 8x+10y=15. NO LINK TO ANSWER PLEASE TYPE
oee [108]

Answer:

x intercept: 15/8 and yintercerpt is 3/2

Step-by-step explanation:

to find y intercept you have to put equation in standard form.

10y=-8x+15

y=--4/5x+3/2

x intercept is when y=0, so we plug in 0

0=-4/5x+3/2

4/5x=3/2

x=15/8
